5. When a bit of baking soda is added in vinegar in a text-tute, a bissing mund
is heurd and several bubbles oudur. The test tube is closed and attached by a
glass tube bo zuther test tube containing lime water. The limewuler slowly
turnus milky in the process. This is shown in the following experimental setup:
Which of the following cannot be considered indicators ar a chemical rewetion
in this experiment?
A) Occurrence of a hissing sound
By The Tommation of several bubbles
C) The change in colour of liquid in tube 2
D) The movement of gas between the test tubes
Answers
Answer:
together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda. The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate. The second reaction is a decomposition reaction.
When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution. ... Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.
Explanation:
: When Baking Soda (NaHCO3) is added to Vinegar (Acetic acid - CH3COOH), it pretends to liberate Carbon dioxide gas. ... When the Carbon dioxide gas is passed through the Lime water [Ca(OH)2], it leads to the formation of Calcium Carbonate (CaCO3) and Water (H2O).22-Oct-2020
